I've never had much luck hunting rub lines. By the time hunting season is in full swing here in eastern, NC just about every-other tree has been hit. I concentrate more on finding a hot scrape line and setting up on that. I guess it depends on what part of the country you are from but hunting rubs are basically useless here. If you are hunting where the deer are not as densley populated then hunting a rub line might produce something for you.
